performance problem cannot be in the onRowSelect event.
Most probably you are doing some kind of a loop in your event handler. If this loop depends on the data in your grid it may perform long enough to hang the browser.
Plreas,e check your event handlers or provide a snippet of a using code, so it can be checked here.
